If you have a need for speed then the Nitecore SC2 is the charger for you. This dual-battery unit can charge at 0.5, 1, 2, and 3 amps. That makes it the fastest charger on the list (again, you need to make sure your batteries can handle the amperage).
Not only is this charger fast, it’s versatile too. In addition to being a safe, accurate, and zippy battery charger for vaping, the Nitecore SC2 can handle NiMH and NiCD batteries. It can also serve as a USB power bank in a pinch.
The display and user interface of the Nitecore SC2 is unusual. Instead of an alphanumeric display and battery gauges, each bay has two columns of lights. The position of the lights shows the charging rate and battery life. This requires some learning and doesn’t provide information in the most straightforward manner. That said, certain vapers will gladly take funky UI in exchange for the SC2’s mercurial capabilities.
